Meanwhile, legislatures in such states as Arizona are considering measures to have more authority over electoral results and local election officials. If that happens, those state assemblies could overturn locally certified results and send their amended electoral college votes to Congress. If these slates were submitted before the safe harbor deadline, Congress might not be able to challenge those, even if both the House and the Senate agreed to do so. Although the 2004 and 2020 electoral vote challenges targeted states that had met the deadline, the disputes’ constitutionality never reached the Supreme Court, perhaps because they were voted down both times. But it may reach the court eventually.
